X4zol™-J Fiber

A Revolution in Comfort

What if the next generation of apparel offered a better fit, with comfortable stretch and support, as well as cooling, breathability, and a sense of weightlessness on the body? It may be time for a revolution in comfort, driven by an innovative new fiber: Lubrizol’s X4zol™-J.

X4zol-J™ Fiber

Lubrizol X4zol™-J, a thermoplastic polyurethane (TPU), is a new elastomeric monofilament that is manufactured differently from spandex, resulting in unique qualities that provide comfort above and beyond traditional stretch fibers. X4zol™-J is produced through a process of melt extrusion, which does not require the use of solvents. The melt extrusion process is cleaner; resulting in a finer and stronger monofilament than traditional spandex, exhibiting a superior stretch.

Spandex vs. X4zol-J™ Fiber

Most spandex fibers exhibit a steeper stress/strain curve, illustrating low initial resistance to stretch, or elongation; and then a rapid increase in resistance to the point of full elongation, or breakage.

Benefits of X4zol-J™ in Fabrics

Thinner and lighter, yet stronger and more durable

Comfortable compression

Breathable and cooling touch

Balanced 360° compression for enhanced fit

Sustainable benefits include processing at lower temperatures and recyclable* fiber
